    27. 27. What is Dissemination? • The vital importance of receiving, synthesizing and communicating online information is increasing dramatically in our current digital age. • Dissemination (from the Latin dissēminātus = ―sowing seeds‖, ―scatter wildly in every direction‖) refers to the process of broadcasting a message to the public without direct feedback from the audience. • Takes on the view of the traditional view of communication which involves a sender and a receiver. • The message carrier sends out information to many in a broadcasting system (composed of more than one channels). • Harmsworth et al. (2000) define dissemination as the ―delivering and receiving of a message‖, ―the engagement of an individual in a process‖ and ―the transfer of a process or product‖.

    103. 103. Social Network vs. Online Discussion Groups • ODG have a limited number of members; • ODG are intended for a smaller number of people to collaborate (Facebook places the number at 250 members); • ODG have a specific purpose – a goal that unites all members, i.e. a discussion topic. • In ODG the number of members and the ideas of the members are known to all participants. • ODG have a creator/owner recognized by all members; • ODG follow a set of rules determined by the administrator, moderator or owner; • In ODG members may have different roles: administrator, moderator, owner, participant, etc.www.sti-innsbruck.at 103
    104. 104. Social Network vs. Online Discussion Groups • Moderators and administrators ensure that the ODG‘s internal code of conduct is followed; • In ODG all members have access to the same shared resources; • ODG members do not have to be connected with the other members (other than the group) to communicate • SN vary in size and heterogeneity; • In SN different members have access to different resources (e.g. some members might have restricted access to a friend‘s photo archive); • In SN members do not know how many participant exist, or who they are;www.sti-innsbruck.at 104
    105. 105. Semantic Based Dissemination What is semantic web? • An extension of the current web in which information is given a well defined meaning, better enabling computers and people to work in cooperationwww.sti-innsbruck.at 105
    106. 106. Semantic Based Dissemination Why use semantics? • Problems with current day search engines: – Recall issues – Results are dependent on the vocabulary – Results are single Web pages – Human involvement is necessary for result interpretation – Results of Web searches are not readily accessible by other software tools • Content is not machine-readable: – It is difficult to distinguish between: ―I am a professor of computer science.‖ and ―You may think, I am a professor of computer science. Well, actually. . .‖www.sti-innsbruck.at 106
    107. 107. Semantic Based Dissemination The Semantic Web Approach • Represent Web content in a form that is more easily machine-processable. • Use intelligent techniques to take advantage of these representations. • Knowledge will be organized in conceptual spaces according to its meaning. • Automated tools for maintenance and knowledge discovery • Semantic query answering • Query answering over several documents • Defining who may view certain parts of information (even parts of documents) will be possible. • Semantic Web does not rely on text-based manipulation, but rather on machine- processable metadatawww.sti-innsbruck.at 107

    109. 109. Semantic Based Dissemination Implementations – Rich Snippets • Implementation realization of an application, plan, idea, model, or design. • Snippets—the few lines of text that appear under every search result—are designed to give users a sense for what‘s on the page and why it‘s relevant to their query. • If Google understands the content on your pages, we can create rich snippets— detailed information intended to help users with specific queries.www.sti-innsbruck.at 109

    111. 111. Semantic Based Dissemination • A (Semantic Web) vocabulary can be considered as a special form of (usually light- weight) ontology, or sometimes also merely as a collection of URIs with an (usually informally) described meaning*. – URI = uniform resource identifier – Semantic vocabularies include: FOAF, Dublin Core, Good Relations, etc. • Format is an explicit set of requirements to be satisfied by a material, product, or service. – The most known examples are RDF and OWL. • Implementation realization of an application, plan, idea, model, or design. – OWLIM - a family of semantic repositories, or RDF database management system * http://semanticweb.org/wiki/Ontologywww.sti-innsbruck.at 111
    112. 112. Semantic Based Dissemination Format • an explicit set of requirements to be satisfied by a material, product, or service. • is an encoded format for converting a specific type of data to displayable information.www.sti-innsbruck.at 112

    114. 114. Semantic Based Dissemination Format – HTML Meta Elements • HTML or XHTML elements which provide structured metadata about a Web page • Represented using the <meta...> element • Can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes • Example: <meta http-equiv="Content-Type" content="text/html" >www.sti-innsbruck.at 114
    115. 115. Semantic Based Dissemination Format – HTML Meta Elements • Search engine optimization attributes: keywords, description, language, robots – keywords attribute - although popular in the 90s, search engine providers realized that information stored in meta elements (especially the keywords attribute) was often unreliable and misleading, or created to draw users towards spam sites – description attribute - provides concise explanation of a Web pages content – the language attribute - tells search engines what natural language the website is written in – the robots attribute - controls whether or not search engine spiders are allowed to index a page, and whether or not they should follow links from a pagewww.sti-innsbruck.at 115
    116. 116. Semantic Based Dissemination Format – HTML Meta Elements • Example - metadata contained by www.wikipedia.org: <meta charset="utf-8"> <meta name="title" content="Wikipedia"> <meta name="description" content="Wikipedia, the free encyclopedia that anyone can edit."> <meta name="author" content="Wikimedia Foundation"> <meta name="copyright" content="Creative Commons Attribution-Share Alike 3.0 and GNU Free Documentation License"> <meta name="publisher" content="Wikimedia Foundation"> <meta name="language" content="Many"> <meta name="robots" content="index, follow"> <!--[if lt IE 7]> <meta http-equiv="imagetoolbar" content="no"> <![endif]--> <meta name="viewport" content="initial-scale=1.0, user-scalable=yes">www.sti-innsbruck.at 116
    117. 117. Semantic Based Dissemination Format – RDFa • Is a W3C Recommendation that adds a set of attribute-level extensions to XHTML for embedding rich metadata within Web documents. • Adds a set of attribute-level extensions to XHTML enabling the embedding of RDF triples; • Integrates best with the W3C meta data stack built on top of RDF • Benefits [Wikipedia RDFa, n.d.]: – Publisher independence: each website can use its own standards; – Data reuse: data is not duplicated - separate XML/HTML sections are not required for the same content; – Self containment: HTML and RDF are separated; – Schema modularity: attributes are reusable; – Evolv-ability: additional fields can be added and XML transforms can extract the semantics of the data from an XHTML file; – Web accessibility: more information is available to assistive technology. • Disadvantage: the uptake of the technology is hampered by the web- master‘s lack of familiarity with this technology stackwww.sti-innsbruck.at 117
    118. 118. Semantic Based Dissemination Format – RDFa • RDFa Attributes: – about and src – a URI or CURIE specifying the resource the metadata is about – rel and rev – specifying a relationship or reverse-relationship with another resource – href and resource – specifying the partner resource – property – specifying a property for the content of an element – content – optional attribute that overrides the content of the element when using the property attribute – datatype – optional attribute that specifies the datatype of text specified for use with the property attribute – typeof – optional attribute that specifies the RDF type(s) of the subject (the resource that the metadata is about).www.sti-innsbruck.at 118
    119. 119. Semantic Based Dissemination Format – RDFa • Example <div xmlns:dc=http://purl.org/dc/elements/1.1/ about="http://www.example.com/books/wikinomics"> <span property="dc:title">Wikinomics</span> <span property="dc:creator">Don Tapscott</span> <span property="dc:date">2006-10-01</span> </div>www.sti-innsbruck.at 119
    120. 120. Semantic Based Dissemination Format – OWL • Family of knowledge representation languages for authoring ontologies • WebOnt developed OWL language • OWL based on earlier languages OIL and DAML+OIL • Characterized by formal semantics and RDF/XML- based serializations for the Semantic Web • Endorsed by the World Wide Web Consortium (W3C) Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 120
    121. 121. Semantic Based Dissemination OWL Sublanguages • The W3C-endorsed OWL specification includes the definition of three variants of OWL, with different levels of expressiveness (ordered by increasing expressiveness): – OWL Lite - originally intended to support those users primarily needing a classification hierarchy and simple constraints Each of these sublanguage – OWL DL - was designed to provide the maximum expressiveness is a syntactic extension of possible while retaining computational completeness, decidability, and the availability of practical reasoning algorithms. its simpler predecessor. – OWL Full - designed to preserve some compatibility with RDF Schema • The following set of relations hold. Their inverses do not. – Every legal OWL Lite ontology is a legal OWL DL ontology. – Every legal OWL DL ontology is a legal OWL Full ontology. – Every valid OWL Lite conclusion is a valid OWL DL conclusion. – Every valid OWL DL conclusion is a valid OWL Full conclusion. • Development of OWL Lite tools has thus proven almost as difficult as development of tools for OWL DL, and OWL Lite is not widely used Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 121
    122. 122. Semantic Based Dissemination Format – OWL • Class Axioms – oneOf (enumerated classes) – disjointWith – sameClassAs applied to class expressions – rdfs:subClassOf applied to class expressions • Boolean Combinations of Class Expressions – unionOf – intersectionOf – complementOf • Arbitrary Cardinality – minCardinality – maxCardinality – cardinality • Filler Information – hasValue Descriptions can include specific value information Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 122
    123. 123. Semantic Based Dissemination Format – OWL • Example: <owl:Class> <owl:intersectionOf rdf:parseType=" collection"> <owl:Class rdf:about="#Person"/> <owl:Restriction> <owl:onProperty rdf:resource="#hasChild"/> <owl:allValuesFrom> <owl:unionOf rdf:parseType=" collection"> <owl:Class rdf:about="#Doctor"/> <owl:Restriction> <owl:onProperty rdf:resource="#hasChild"/> <owl:someValuesFrom rdf:resource="#Doctor"/> </owl:Restriction> </owl:unionOf> </owl:allValuesFrom> </owl:Restriction> </owl:intersectionOf> </owl:Class> Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 123
    124. 124. Semantic Based Dissemination Format – OWL 2 • Extends OWL 1 • Inherits OWL 1 language features • Makes some patterns easier to write • Does not change expressiveness, semantics and complexity • Provides more efficient processing in implementations • Syntactic sugar: – DisjointUnion - Union of a set of classes; all the classes are pairwise disjoint – DisjointClasses - A set of classes; all the classes are pairwise disjoint – NegativeObjectPropertyAssertion - Two individuals; a property does not hold between them – NegativeDataPropertyAssertion - An individual; a literal; a property does not hold between them • OWL 2 allows the same identifiers (URIs) to denote individuals, classes, and properties • Interpretation depends on context • A very simple form of meta-modelling Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 124
    125. 125. Semantic Based Dissemination Format – OWL 2 • New constructs for properties: – Self restriction: Classes of objects that are related to themselves by a given property – Qualified cardinality restriction: Qualifies the instances to be counted – Object properties – Disjoint properties – Property chain: Properties can be defined as a composition of other properties – keys • An OWL 2 profile (commonly called a fragment or a sublanguage in computational logic) is a trimmed down version of OWL 2 that trades some expressive power for the efficiency of reasoning. • OWL 2 profiles – OWL 2 EL is particularly useful in applications employing ontologies that contain very large numbers of properties and/or classes. – OWL 2 QL is aimed at applications that use very large volumes of instance data, and where query answering is the most important reasoning task – OWL 2 RL is aimed at applications that require scalable reasoning without sacrificing too much expressive power. • OWL 2 profiles are defined by placing restrictions on the structure of OWL 2 ontologies.

    127. 127. Semantic Based Dissemination Format – RIF • A collection of dialects (rigorously defined rule languages) • Intended to facilitate rule sharing and exchange • RIF framework is a set of rigorous guidelines for constructing RIF dialects in a consistent manner • The RIF framework includes several aspects: – Syntactic framework – Semantic framework – XML framework • RIF can be used to map between vocabularies (one of the proposed use cases) Source: Michael Kifer State University of New York at Stony Brookwww.sti-innsbruck.at 127
    128. 128. Semantic Based Dissemination Format – RIF • The standard RIF dialects are: – Core - the fundamental RIF language. It is designed to be the common subset of most rule engines. (It provides "safe" positive datalog with builtins.) – BLD (Basic Logic Dialect) - adds a few things that Core doesnt have: logic functions, equality in the then-part, and named arguments. (This is positive Horn logic, with equality and builtins.) – PRD (Production Rules Dialect) - adds a notion of forward-chaining rules, where a rule fires and then performs some action, such as adding more information to the store or retracting some information. • Although RIF dialects were designed primarily for interchange, each dialect is a standard rule language and can be used even when portability and interchange are not required. • The XML syntax is the only one defined as a standard for interchange. Various presentation syntaxes are used in the specification, but they are not recommended for sending between different systems.

    130. 130. Semantic Based Dissemination Format – Microformats • Directly use meta tags of XHTML to embed semantic information in web documents; • Microformats were developed as a competing approach directly using some existing HTML tags to include meta data in HTML documents • As of 2010, microformats allow the encoding and extraction of events, contact information, social relationships and so on • Advantages: – you can publish a single, human readable version of your information in HTML and then make it machine readable with the addition of a few standard class names – No need to learn another language – Easy to add • However: they overload the class tag which causes problems for some parsers as it makes semantic information and styling markup hard to differentiatewww.sti-innsbruck.at 130
    131. 131. Semantic Based Dissemination Format - Microformats • Example <ul class="vcard"> <li class="fn">Joe Doe</li> <li class="org">The Example Company</li> <li class="tel">604-555-1234</li> <li><a class="url“ href="http://example.com/">http://example.com/</a></li> </ul>www.sti-innsbruck.at 131
    132. 132. Semantic Based Dissemination Format – Microdata • Use HTML5 elements to include semantic descriptions into web documents aiming to replace RDFa and Microformats. • Introduce new tag attributes to include semantic data into HTML • Unless you know that your target consumer only accepts RDFa, you are probably best going with microdata. • While many RDFa-consuming services (such as the semantic search engine Sindice) also accept microdata, microdata-consuming services are less likely to accept RDFa. • Advantages: – the variable groupings of data within published area tables may not be the detail required for a particular application (e.g. age group, ethnic group or occupational classification). – the cross-tabulations of variables available in area tables may not be those needed for a study (e.g. counts of individuals by age and ethnic group and occupation).www.sti-innsbruck.at 132
    133. 133. Semantic Based Dissemination Format – Microdata • Examples: – Google may use microdata in its results pages: – Opera from version 11.60 is the only current stable release of a browser that supports microdata: – MicrodataJS is a JavaScript library and jQuery plugin that emulates the DOM API.www.sti-innsbruck.at 133

    136. 136. Semantic Based Dissemination Format – RDF • The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. • RDF provides a common framework for expressing information so it can be exchanged between applications without loss of meaning. • It is based on the idea of identifying things using Web identifiers (called Uniform Resource Identifiers, or URIs) and describing resources in terms of simple properties and property values • Thus, RDF can represent simple statements about resources as a graph of nodes and arcs representing the resources, and their properties and values. • It specifically supports the evolution of schemas over time without requiring all the data consumers to be changed Source: http://www.iis.sinica.edu.tw/~trc/public/courses/Fall2008/week15/slide-w15.html#%287%29www.sti-innsbruck.at 136
